Clement (1453)
Traditionally the name "apostle" is reserved for a smaller group of Jesus' followers, namely Peter, Andrew, James the Greater, James the Lesser, John, Philip, Bartholomew, Matthew, Thomas, Thaddeus, Simon, and Judas Iscariot. Later on Matthias replaced Judas. Saints with a special mission are also known as apostles, e. g. , St. Paul.
